I haven't gone through every post... but it seems to me that we have yet to mention that guy from Ranma 1/2 episode 106 who practices Martial Arts Dining. He's a bit character though, so it makes sense that he hasn't been mentioned...

("Martial Arts Dining: this style gives a whole new meaning to "food fight". The objective is to be the first one to clear all of the many plates of food you're given — and, for an extra twist, you must be incredibly neat about it. As in, you can't be seen to actually eat the food — if you're spotted, you get an extra plate as a penalty. As a result of centuries of adherence to these insane rules, practitioners have faces that they can warp and stretch like silly putty, as well as super-speed hand-strikes. Swallowing watermelons whole, picking a sweet from the top of one's own head with one's tongue and then swallowing it, all of these are possible" http://tvtropes.org/pmwiki/pmwiki.php/Main/MartialArtsAndCrafts )
